Gaming performance

Let's see how good Core i7-640M and Core M-5Y31 are for gaming compared with game system requirements. Remember that sometimes official requirements may reflect real performance inaccurately.

Advantages of Intel Core i7-640M

4.9% faster in synthetic tests
Higher maximum frequency (3467 vs 2400 MHz)
Enhanced SpeedStep (saves energy by managing CPU frequency and voltage in realtime. Supercedes SpeedStep)
AES (Advanced Encryption Standard instructions set - hardware acceleration of AES encryption and decryption. Speeds up encryption software, e.g. Veracrypt)
x86-64 (a general name for 64-bit extension of x86 instruction set. There are AMD64 and Intel 64 versions that differ very little)
TXT (Trusted Execution Technology - protects the system against viruses and rootkits residing in BIOS or in a boot sector)
vPro (a marketing umbrella term for several Intel technologies: AMT, TXT, EDB, VT, Anti-Theft and some others)
FMA4

Advantages of Intel Core M-5Y31

Much newer (27 October 2014 vs 1 September 2010)
Finer manufacturing process technology (14 vs 32 nm)
Less power hungry (5 vs 35 watts)
HyperThreading (allows one physical CPU function as two logical ones. It increases performance, since while one logical CPU is waiting for data, the second may still do useful work)
AVX (Advanced Vector Extensions - a set of SIMD instructions working with 128- and 256-bit registers)
AVX2 (Advanced Vector Extensions 2 - an extension to AVX, the set of SIMD instructions working with 128- and 256-bit registers)
Quick Sync (hardware acceleration of video encoding and decoding for Intel CPUs. Speeds up video encoding by times, but at the cost of somewhat lower quality)
Virtualization (Hardware acceleration of virtual machines)
AES-NI (Advanced Encryption Standard New Instructions - additional instructions for hardware acceleration of AES encryption and decryption)
Intel 64 (64-bit Intel CPU architecture. Almost identical to AMD64, except small and rarely used nuances)
